Who Knows Activity

Write down the following words/problems on a piece of paper. Leave enough room to write definitions or work the problems, but dont answer them yet.

1. Displacement
2. Meniscus
3. Lab Safety
4. Solid (Volume, _Shape)
5. Liquid (Volume, _Shape)
6. Gas (Volume, _Shape)
7. Molar Mass
8. Mole
9. How many moles are in 50 g of Iodine?
10. How many g are in 32 moles of Barium
11. What is the density of an object whose mass is 47 g and whose volume is 36 mL?
12. Is density an intensive physical property or an extensive one?
13. Intensive physical property
14. Extensive physical property
15. Physical Change
16. Chemical Change
17. How many significant figures in 320000
18. How many significant figures in .00004030
19. How do you write 5030000000000 in scientific notation?
20. Copy the heat curve on the board... does it show that it takes more heat to melt or boil water?
21. If you have to heat an object with 4030 J of energy to raise its temperature from 50 degrees C to 73 degrees C, and it has a mass of 693 g, what is its specific heat?
22. If you have an object with a specific heat of 1.8 J/gC and it has a mass of 53g, how much heat do you need to raise its temperature from 34 to 80 degrees celcius?
23. What does Q represent, and what unit do you use for it?
24. Element (define & give an example)
25. Compound (define & give an example)
26. Homogenous Mixture (define & give an example)
27. Heterogeneous Mixture (define & give an example)
28. Distillation
29. Chromatography
30. Filtration
31. Evaporation
32. sublimation
33. condensation
34. These words mean what kind of change? (Reacts, produces, corrodes, decomposes, precipitates, combusts, burns, bubbles a gas, oxidizes, explodes, tarnish, ferment)
35. These words mean what kind of change? (Change in shape, cutting, tearing, crushing, bending, dissolving, or change in state of matter)

If you know all this stuff, you will be good for the test! Learn it all! =)

Activity Rules

1. You cannot sit down
2. You must ask someone to TELL you the answer. You will WRITE what they TELL you.
   1. They do not write it
   2. They do not show you what they have written down.
3. You may only use each person TWICE. Get an initial from each person as they tell you what the answer is.
4. Do not say "do you know number 4?" Thats lame. Ask the whole question. "Do you know the definition of solid?" For the long math ones, ask "Do you know how to solve the heat question?" or something like that.

FYI, once someone has told you an answer, you now know it and may tell someone else.
